Strictly from a viewer’s perspective, I use a YouTube client alternative (like GrayJay, Freetube, NewPipe) and subscribe only to the channels I want to see content from. Then I can look at video suggestions for given videos to see relevant content. This entirely removes me from the algorithm as well as any personalization that would put me in an echo chamber. I also branch out to reliable and unbiased news sources, better search engine alternatives, and so on.
I’m clearly out of touch with the world. Over half of these got an audible groan out of me when I watched the trailers.
